INTRODUCTORY
The main objects of this work are to place on record the results of investigations made among the native tribes in British East Africa, particularly among the Kikuyu and Kamba people, and to endeavour, from a study of their ceremonial with regard to sacrifice and taboo, to obtain a better insight into the principles which underlie the outward forms and ceremonies of their ritual.
It has long been customary, partly through narrow-minded prejudice and partly through ignorance, to class as Pagans all native tribes which have not yet embraced one of the great positive religions, such as Christianity or Mohammedanism. But the time has now come when such negative definitions, if seriously applied, will have to be abandoned. It must be admitted that all savages have a natural religion which is a survival of, and is analogous to, a stage of belief which existed among the ancestors of the civilised peoples of the present day. The admission is inevitable, however distasteful to those who are dogmatic in their religious beliefs and loath to admit that religious thought and the conception of a deity have passed through an evolutionary process and, furthermore, a process which has not ceased. For, after all, the development of mental and moral ideas is a part of the evolution of the living being as much as the development of limbs, cranial shape, or body markings. No positive system of religion descended from heaven as a completely new concept of the deity and with an absolutely novel code. Such a system could never have survived. Any new religious teacher could not fail to be, to a great extent, a [[20]]creature of his environment and of the age in which he was born. He must necessarily graft his scheme on to what went before. As Robertson Smith so truly says, “a new scheme of faith can only find a hearing by appealing to religious instincts and susceptibilities that already exist in the audience.”
In East Africa, various tribes remain in a stage of belief very similar to that which prevailed in Arabia and Assyria from about 1500 B.C. and onward, and which continued till a dogmatic uniformity was forced on the bulk of the people by the teachings of Mahomed about A.D. 650.
Asiatic beliefs were introduced to Abyssinia by the Sabæans or Himyaritic invaders a few centuries before the Christian era, but it is doubtful whether they spread to any extent. For ancient religious influences on Central Africa, we must look more to the channel afforded by the Nile valley which had become a route of exploration as far back as the time of the Pharaohs. Although, however, we know that Egyptian influence was spasmodically exercised for a long distance up the Nile valley, little evidence of any spiritual effect has as yet come to light. This is natural, for the ancient expeditions were at long intervals and were not missionary enterprises, but were in search of material gain.
The only case of permanent settlement which appears to be beyond doubt is the invasion into Uganda, Unyoro, and Ankole, of a light coloured race, now known as the Ba-Hima or Ba-Huma. Some consider that these people came from the Abyssinian highlands; Sir Harry Johnston, on the other hand, believes them to be descendants of ancient Egyptian settlers; according to Dr Seligman they are probably descendants of what he terms Proto-Egyptians—the latter description being a more concrete definition based upon careful researches in the Nile valley, the result of which was not available when Sir H. H. Johnston made his suggestion.
But whatever the origin of the Ba-Hima, there [[21]]appears to be no trace of this infusion of northern blood anywhere east of the Rift Valley, except, possibly, among the Masai who are believed to have migrated south-east from the valley of the Upper Nile. The Nandi, the Lako and Savei of Elgon, the Lumbwa and Elgeyo also came from the north-west, but did not cross the Rift.
The Kikuyu absorbed some Masai blood from time to time, and also intermixed to some extent with the aboriginal Oggiek, but they are mainly Bantu in blood and constitution. The Kamba people, whose ancestors flowed into their present habitat from the south and south-west, are believed to be pure Bantu.
